What I want to do is get this

url="http://www.ubcmiami.org/podcasts/Storming%20the%20Gates%20of%20Hell_%20Your%20Adversary%2C%20the%20Devil.mp3"

which is in the xml file however i want to use php just to grab the url and not the quotes or anything like that. Any idea how I could do that? I tried using stripos, but was lost in how to just get whats in the quotes. Any help will be greatly appreciated.

Thanks

if you are using php5 you can use php built-in functions.

You can also use regular exressions. It will probably be less memory usage then SimpleXML but may be slower.

preg_match_all("/<enclosure type=\"audio\/mpeg\" url=\"([^\"]+)\" length=\"[0-9]+\" \/>/", $xml, $matches);

$urls = $matches[1];

http://php.net/preg_match

digital-ether 399 Nearly a Posting Virtuoso Team Colleague · Answer 2 · 2009-03-19T03:25:52+00:00

Turns out preg_match() is a lot faster then using SimpleXML.

function benchMark($function, $arg = null, $loops = 1000) {
	echo 'Benchmarking: '.$function.': ';
	$start = microtime(1);
	for($i = 0; $i < $loops; $i++) {
		$function($arg);
	}
	$exec_time = microtime(1)-$start;
	echo $exec_time.'<br />';
	return $exec_time;
}

function preg_find($rss) {
	preg_match_all("/<enclosure type=\"audio\/mpeg\" url=\"([^\"]+)\" length=\"[0-9]+\" \/>/", $rss, $matches);
	return $matches;
}

function str_find($rss) {
	$offset = 0;
	$i = 0;
	$len = strlen($rss);
	
	$search = '<enclosure type="audio/mpeg" url="';
	$searchl = strlen($search);
	
	$urls = array();
	while($start = strpos($rss, $search, $offset)) {
	
		$start = $searchl+$start;
		$end = strpos($rss, '"', $start);
		$substr = substr($rss, $start, $end-$start);
	
		$urls[] = $substr;
		$offset = $end+1;
	
	}
	return $urls;
}

function simplexml_find($rss) {
	$xml = new SimpleXMLElement($rss);
	$encs = $xml->xpath('/rss/channel/item/enclosure');
	$urls = array();
	foreach($encs as $enc) {
		$urls[] = $enc->attributes()->url;
	}
	return $urls;
}


benchMark('preg_find', $rss, 10000);
benchMark('str_find', $rss, 10000);
benchMark('simplexml_find', $rss, 10000);

Results:

Benchmarking: preg_find: 1.3141620159149
Benchmarking: str_find: 0.49334096908569
Benchmarking: simplexml_find: 4.6836819648743

Using strpos() and substr() being the fastest by far.

function str_find($rss) {
	$offset = 0;
	$i = 0;
	$len = strlen($rss);
	
	$search = '<enclosure type="audio/mpeg" url="';
	$searchl = strlen($search);
	
	$urls = array();
	while($start = strpos($rss, $search, $offset)) {
	
		$start = $searchl+$start;
		$end = strpos($rss, '"', $start);
		$substr = substr($rss, $start, $end-$start);

	}
	return $urls;
}

You can turn this into a generic function to find all strings between two strings.

/**
 * Find all sub-strings between two strings in a given string
 * @return Array
 * @param $text String Haystack to Search
 * @param $start_str String Start String
 * @param $end_str String End String
 */
function str_search($text, $start_str, $end_str) {
	$offset = 0;
	$i = 0;
	$len = strlen($text);
	$searchl = strlen($start_str);
	$matches = array();
	while($start = strpos($text, $start_str, $offset)) {
		$start = $searchl+$start;
		$end = strpos($text, $end_str, $start);
		$substr = substr($text, $start, $end-$start);
		$matches[] = $substr;
		$offset = $end+1;
	}
	return $matches;
}

Thanks for the advise I didnt realize it was that much faster. I am using simple xml, and here is my code but i might change to what you used.

<?php // Load and parse the XML document 
$rss =  simplexml_load_file('http://www.ubcmiami.org/podcasts/podcast.xml');
$title =  $rss->channel->title;

// Here we'll put a loop to include each item's title and description
foreach ($rss->channel->item as $item) {
	if($count <= 0)
	{

		$media = $item->guid;
  		$count++;
	}
}
